Math and physics study app

Coming back to math or physics? Find out how much you can rebuild.

Whether you studied it years ago or you’re in the middle of a course, Unisium has you recall each principle, explain why it works, and use it to solve problems. You see which ideas hold up and which need work.

A real kinematics study attempt shows a question about when the equation applies, a submitted answer naming constant acceleration, and AI feedback asking for that condition across the whole time interval. — **Elaborative encoding:** A real study attempt: a spoken explanation becomes a committed answer, followed by AI feedback.

Coming back after years away

You studied math or physics once and want it back, for a degree, a new career, or because you miss it. Start where you are and see what you still know.

Taking the course now

The lectures and examples make sense, but solving on your own is harder. Practise the step from understanding a solution to producing one.

How Unisium works

Unisium organizes each subject around named principles, such as Newton’s second law. Each study card works on one of four abilities for a principle.

Connect

Know when it applies

Answer questions about what an equation means, when it applies and how it differs from another principle.

Retrieve

Recall it without looking

Recall a principle, its equation and when it applies, before you see the answer.

Explain

Say why a solution works

Explain why the principles in a worked solution apply and how its steps reach the answer.

Solve

Solve it yourself

Choose the principles, do the mathematics and get your final answer checked.

How progress works

Each principle has four scores. Connect, Retrieve, Explain and Solve are tracked separately, so knowing an equation does not count as being able to use it.
Harder work moves you faster. Strong answers on harder tasks can raise your level more quickly than repeating easy ones.
Ideas come back. Principles return for review and in other kinds of tasks, so what you learned earlier keeps getting practice.
Rewards come from study. Completed study earns resources and can unlock scientist collection cards.

“Unisium has changed the way I solve problems. At first, I felt a lot of pressure, but now I remember more and feel more productive. Solving even one real problem is helpful, and math feels much easier now.”

Questions

Does Unisium work on mobile?

Yes for lighter study modes like retrieval and quick review. More scratchpad-heavy problem solving is usually better on desktop or tablet.

Is Unisium only for math?

No. Unisium covers both math and physics.

Do I need to join the mailing list to start?

No. Choose a plan on the pricing page to start a trial. The mailing list is optional.
